JOHN MATSON AND JAMES C. MATSON, OF BROOKVILLE, PENNSYLVANIA.

CHURN.

SPECIFICATION forming part of Letters Patent No. 316,988, dated May 5, 1885.

Application filed November 12, 1884. (N0 model.)

To all whom it may concern:

Be it known that we, JOHN MATSON and J. O. MATSON, citizens of the United States, residing at Brookville, in the county of J efferson and State of Pennsylvania, have invented certain new and useful Improvements in Ghurns; and We do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

The object of this improvement is to increase the efficiency of concentric dasher frame churns by providing the same with features of construction that will enable the dashershaft and frames to be conveniently removed from the barrel of the churn, and the parts entirely disconnected from each other for the purpose of being thoroughly scalded and cleaned, and thus be kept in more perfect order than is otherwise practicable. These results are attained by the mechanism illustrated in the drawings herewith filed as part hereof, in which the same letters of reference denote the same parts in the different views.

Figure 1 is a side elevation, partly in section, representing a churn embodying the features of our improvement. Fig. 2 is aview as seen from the top of the lid, with some of the parts cut away for the purpose of more fully illustrating features of construction and their relative position. Fig. 3 is a vertical section as seen from the side opposite to that shown in Fig. 1.

A is the churn-barrel, centrally secured to the bottom of which is a metal socket or shaftbearing, a. p

B is the dasher-shaft, to be made preferably of hard close-grained wood, and provided at its lower end with a flanged metal thimble, B, having a reduced extension fitting the socketa, as shown in Fig. 1, and secured to the shaft B by atransverse pin, 1), which causes the thimble to turn with the shaft and prevent it from being worn by contact with the socket a.

G O are transverse pieces and G C are vertical pieces composing the inner dasher-frame. The parts 0 0 have enlargements c a, perforated to fit closely over the shaft B, to which they are rigidly secured in the positions shown by means of ordinary wood-screws, 0 c. The vertical pieces or dasher blades 0 O are halved or matched to the ends of the transverse parts 0 G, and secured in position by screws D D are transverse pieces and D D are vertical pieces composing the outer dasherframe, and are connected at their ends, as shown at d, in the same manner as the parts 0 G. The lower piece, D, of the outer frame has an enlargement, d, perforated to fit loosely over the shaft B, and the piece D has an enlargement, d perforated to fit closely around a sleeve, E, or reduced extension from the hub of the bevel-gear E, which meshes with a corresponding gear, F, secured to a horizontal shaft, f, supported by a pillow-block, F, and provided at its outer end with a momentumwheel having a crank or operating-handle, f The gear F is secured to the shaft f by a setscrew, g.

G is a bevel-gear secured to shaft B by setscrew in position to mesh with the gear F.

H H represent the churn-lid,divided at the center into two equal parts, hinged together at one side, as shown at h, and provided in the center with semicircular recesses to fit around the extension E of the gear E.

I I are metal plates secured to the churn-lid by wood-screws, i, and flanged downward, as shown at I "1, and provided with thumbscrews I I for securing the lid to the churnbarrel.

K is a spring secured to the churn-lid H by wood-screw k and provided at its other end with an inward extension, as shown at K, which springs over the downward extension I of the plate I and holds the parts H H of the churn-lid together.

J is a spring curved to fit the sleeve or reduced extension E of the gear E, and is secured to the lid-half H by means of a twisted end, as shown at J, in a suitable position to make the curved end J bear against the sleeve E with sufficient tension to hold the shaft B and gearing E G in position to mesh with the gear E. The upper edge of the spring J engages with the hub of the gear E, and operates as a bearing for the same, and prevents the ICO churn-lid from being worn by contact thereeration of our improvement, what we claim as with. The thimble B at the lower end of the shaft 13 prevents the latter from wearing away, and also operates as a support for holding the outer (flasher-frame in proper relative position with the gear E.

By reason of the lid H H being arranged to open in the center the dasher-shaft and connecting-frames may be easily removed from the churn-barrel, after which the parts may be disconnected from the shaft B and from each other and thoroughly scalded for the purpose of keeping the same in perfect order.

Motion given to the mechanism through the driving-shaft f and gear F will operate the dasher-blades in opposite directions as in all churns having concentric dashers.

Having explained the construction and op- JOHN MATSON, JAMES C. MATSON.
